msm: kgsl: always check ft and hw gates in kgsl_active_count_get

The device state can fluctuate during recovery and resume, so
it is safer to check the gates unconditionally rather than
trust the state. The gates are left open until recovery
or suspend starts.

msm: kgsl: Do not wait for FT gate in fault tolerance state

When device start fails, device is in INIT state and FT is triggered.
In FT we trigger snapshot which waits on ft_gate when active count is
0 and device is not in active state. This causes a deadlock. This
change does not wait for FT gate in FT state and thereby prevents
the deadlock.

sync: signal pt before sync_timeline object gets destroyed

There is a race condition

Assume we have *one* sync_fence object, with *one* sync_pt
which belongs to *one* sync_timeline, given this condition,
sync_timeline->kref will have two counts, one for sync_timeline
(implicit) and another for sync_pt.

Assume following is the situation on CPU

Theead-1 : (Thread which calls sync_timeline_destroy())
  -> (some function calls)
   -> sync_timeline_destory()
    -> sync_timeline_signal() (CPU is inside this
function after putting reference to sync_timeline)

At this time Thread-2 comes and does following

Thread-2 : (fclose on fence fd)
> sync_fence_release() -> because of fclose() on fence object
 -> sync_fence_free()
  -> sync_pt_free()
   -> kref_put(&pt->parent->kref, sync_timeline_free);
    -> sync_timeline_free() (CPU is inside this because
this time kref will be zero after _put)

Thread-2 will free sync_timeline object before Thread-1
has finished its work inside sync_timeline_signal.

With this change we signals all sync_pt before putting
reference to sync_timeline object.

Execute shader on wakeup from power collapse

After wakeup from power-collapse, a shader execution is needed
to reset the GPU to a known and stable state on certain targets.
This change implements the required shader execution only
on initialization and on recovery from power-collapse on A3xx
GPU targets.
